SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 278,802, dated June 5, 1883.

Application filed March 20, 1883.

To all whom it may concern:

Be it known that I, J OEN KUBLER, a citizen of the United States, residing at Hot Springs, in the county of Garland and State of Arkansas, have invented certain new and useful Improvements in a Window-Fastener andI do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention has relation to automatic window or sash fasteners; and it consists in the novel construction and arrangement of its parts, and is described as follows:

Figure 1 represents the front inside face of a window-frame, A, holding upper sash, a, and lower sash, b. The sashes are capable of being moved up and down in the frame.

Fig. 2 represents a side view of Fig. 1 cut through at the line 00 w.

Fig. 3 represents screw-stud G. This stud has a screw-point for penetrating the wood and a cylindrical head the same size its entire length.

Fig. 4 represents a spring, B, hereinafter fully described. This spring is secured on the front side of one of the side pieces of the lower frame, I), by means of two ordinary male screws, 0 c. The male screw 0 is used to regulate its pitch. This spring is straight at its upper end for about one-fourth of its length, and fits down tight on the frame to the point indicated by theletter d, Fig. 4. Then it is bent out so that its lower end stands out from the face of the sash about one-half inch. On the lower end of this spring I have an elevation,

0 f, and in this elevation I have a notch, f, to

receive the heads of studs G. The upper and lower edges of the notch f are cut circular in form, so that no amount of pressure up or down will cause it to slip off of the head of the studs. This spring B passes under the studs 0, and the lower end of the spring is flattened out and bent inward to form a thumbpiece, f that the spring maybepressed down to relieve its grasp on the heads of the studs. By means of screw 0", I regulate the pitch of the spring, so that as the sash moves up or (ModeL) the sash tight down or to hold it at any ele vation desired. These studs are screwed into the inner face, D, of the frame A in a straight line, about one and a half inch from the inner face of the lower sash, b. The head of this stud is about one-half an inch long, cylindrical, and of the same size its entire length, so that when screwed home there will be nothing on the head to catch and entangle the curtains or other material coming within its reach. The screws 0 c and c are countersunk into spring B until the upper surface of their heads are even with the face of the said spring. They are enlarged a little in Fig. 2 for the purpose of showing their .position.

The novelty and advantages claimed for my invention are: It is so simple that it can be applied in a few moments of time without the aid of a mechanic. The studs have no enlargements of their heads to catch or entangle the curtains or other material coming in contact therewith, as an ordinary male screw would do. The pitch of the spring can be so regulated by screw 0 as to adapt it to any window-frame, whether it be deep or shallow. The edges of notch f are cut circular, so that it will not slip ofl of the studs.

I claim In combination with the window-frame A and sash b, spring B, secured to the face of the sash by screws 0 c, and having thumb piece f elevation f, and circular notch f with screw 0, regulating the pitch of the spring B, and screw-studs C, secured in the face of the window frame, and engaging. with circular notch f and locking the sash, substantially as shown and described.

In testimony whereof I affiX my signature in presence of two witnesses.

JOHN KUBLER.
